This text is what I wrote out on another forum but may help you also or cross reference etc, some maybe repeted. The TCI plug 4 wires: 1 black=coil terminal 15 and also linked to a black/white wire at coil which will go back the the ecu plug. 1 black (which is brown but has black top cover)=earth on battery 1 green=coil terminal 1 1 brown/blue=goes into the ecu plug The dizzy plug 3 wires: All 3 wires will go back the the ecu plug (nice and easy ) The ecu plug 9 wires: 1 blue/white=water temp switch on side on head 1 brown=earth next to dizzy or where ever you like 1 red/yellow and 1 black/yellow which are linked into a plug at the end of them...not used. The other 5 wires as above/linked to the other plugs. This wiring was used for a 16v in a caddy using a MK1 ISV and not a MK2 one with the control box etc.
